Yet another funny oxymoron. Christian rap really doesn't exist, it's like metal without the sex, drugs and parties. Christian rap will never express some of the core ideals and dilemmas that almost all rap artists express. I'm sorry, but a rap or hip-hop song about Mountain Dew, which is a great drink, is not a rap song. It's like a football player dressed as a ballerina for the Super Bowl, it just isn't right.
Listening to 2Pac can help you understand what real rap is about.
